Compare acidic and basic solutions in terms of their h ion and oh ion concentrations?
In acidic solutions, the H+ ion concentration is higher than the OH- ion concentration. Conversely, in basic solutions, the OH- ion concentration is higher than the H+ ion concentration. The pH scale is used to measure the concentration of H+ ions in a solution.
What is the product of H3O ion and OH- ion concentration in water?
The product of the H3O+ ion concentration and the OH- ion concentration in water is always equal to the ion product of water, which is 1.0 x 10^-14 at 25°C. This relationship is described by the equation [H3O+][OH-] = 1.0 x 10^-14.
How can one determine the concentration of hydroxide ions (OH-) from the concentration of hydrogen ions (H)?
To determine the concentration of hydroxide ions (OH-) from the concentration of hydrogen ions (H), you can use the equation for the ion product of water (Kw HOH-). By knowing the concentration of one ion, you can calculate the concentration of the other ion using this equation.
What is the H ion concentration in a 4.8x10-2 M KOH solution?
To find the H ion concentration in a KOH solution, first determine the hydroxide ion (OH-) concentration. Since KOH is a strong base, it fully dissociates in water. Therefore, the OH- concentration is equal to the KOH concentration, which is 4.8x10^-2 M. The H ion concentration can be calculated using the equation Kw = [H+][OH-], where Kw is the ion product of water (1.0x10^-14 at 25°C). From there, you can determine the H ion concentration by dividing Kw by the OH- concentration.
What is the relationship between the pOH and the OH ion concentration of a solution?
The pOH is the negative logarithm of the hydroxide ion (OH-) concentration in a solution. As the pOH decreases, the OH- concentration increases, and vice versa. The relationship is inverse, meaning as one increases, the other decreases and vice versa.
Compare acidic and basic solutions in terms of their h ion and oh ion concentrations?
In acidic solutions, the H+ ion concentration is higher than the OH- ion concentration. Conversely, in basic solutions, the OH- ion concentration is higher than the H+ ion concentration. The pH scale is used to measure the concentration of H+ ions in a solution.
Which substances decreases the H ion concentration in a solution?
Bases, anything with the OH- ion in the formula.
What is the product of H3O ion and OH- ion concentration in water?

Which term is applied to an aqueous solution whose hydrogen ion concentration H plus is less than its hydroxide ion concentratio OH?
The term applied to an aqueous solution with a hydrogen ion concentration (H+) lower than the hydroxide ion concentration (OH-) is basic or alkaline. This indicates that there are more OH- ions present, making the solution basic on the pH scale.
What is the difference in the amount of hydrogen ion and hydroxide ion in the solution with pH7?
In a solution with pH 7, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-). At this pH, the solution is neutral, meaning the amount of H+ and OH- ions is balanced, resulting in a neutral charge.
What information is necessary to determine the pH of a solution when you given hydroxide ion concentration?
To determine the pH of a solution from the hydroxide ion concentration, you also need the concentration of the hydrogen ion. Once you have that information, you can use the equation pH = 14 - pOH, where pOH is calculated as -log[OH-] and [OH-] is the hydroxide ion concentration.
What expression is used to represent the concentration of OH- ions?
pOH is the expression used to represent the concentration of OH- ions. It is calculated as the negative logarithm of the hydroxide ion concentration in a solution.
At a pH of 7 what is true a The hydroxide ion concentration equals the hydronium ion concentration b The concentration of the acid equal the concentration of the conjugate base?
At a pH of 7, both statements are true. The hydroxide ion concentration equals the hydronium ion concentration in a neutral solution with pH 7. Additionally, in a neutral solution, the concentration of the acid equals the concentration of the conjugate base since the solution has an equal balance of H+ and OH- ions.
How does the POH scale form PH scale?
pH + pOH = 14 pH is a measure of the hydrogen ion concentration, [H+] pOH is a measure of the hydroxide ion concentration, [OH-] pH = -log10[H+] pOH = -log10[OH-]
